All,

I have two file in a one to many relationship. I am trying to restrict insertion of records into a child table unless a parent record exists, but I have found that the act of inserting a record in the child causes the trigger to fail unless I have a dummy record in the parent with a blank key.

Two question:

1 Is there a way to insert a record in the child with the parent key already replaced?

2. Is putting a dummy record in the parent the only way around this problem?

TIA

Rex
